INSOLE-REINFORGING- MACHINE.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed October 21, 1914. Serial No. 867,761.

To all whom it may concern Be it known that I, ALEXANDER M. Ann ANDER, acitizen of theUnited States, residing at Beverly, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in In sole-Reinforcing Machines; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to machines for applying reinforcing fabric tolipped insoles and more particularly to devices in such machines fortrimming the fabric to the contour of the insole.

From the time that reinforcedinsoles of the Gem type, wherein the fabricis beaded or crimped about the lip, were first introduced, and untilrecently, it has been the practice to trim the fabricalong a linecoinciding with the edge of the insole. It has long been recognized thatthe raveled threads showing beyond the edge of theinsole are undesirableas they renderthe sole unsightly and detract from its selling qualities.Various experiments have been made to avoid the trouble with the resultthat it is now coming to be the general practice to trim the fabric,particularly at the shank,

along a line spaced from the edge of the in-v sole, that is, the fabricis trimmed inside of the insole edge instead of at its edge.

The object of the present invention is to provide novel means fortrimming the fabric so as to prevent the fabric on reinforced insolesfrom being seen when viewing the insole from its grain, or unreinforced,side. In accordance with this object the invention contemplates theprovision, in a machine of the character described, of a knife locatedabove the/feather and within its edge, in combination with means beneaththe fabric for supporting it so that it may be cleanly severed by theknife and for also preventing a slitting of the'feather, which wouldweaken the insole. To the accomplishmentof this object, the inventioncomprises the features. and combinations of parts hereinafter describedand particularly defined in the appended claims.

The features of the invention will be best understood from a descriptionof the preferred embodiment thereof illustratedin the accompanyingdrawings, in which the inaway patent is retained,

vention has been shown as applied to the insole reinforcing machineexemplified by Letters Patent of the United States to John B. Hadaway,No. 614,860, dated November 29, 1898. r

In the drawings, Figure l is a side elevation of the machine; Fig. 2 isa detail illustrating the mounting of the fabric trimming knife, and theresultant efiect on an insole; Fig. 3 is an underside view of the knifeand its cooperating plate; and Fig. & is an enlarged detail illustratingthe manner in which the knife cooperates with a slotted plate to shearthe fabric.

The tools for supporting, feeding and forming the bead or crimp in thereinforcing fabric and applying it to the insole, that is, the worktable 1 and its step-by-step feeding mechanism; the inside and outsideforming tools 2 and 8 respectively and their operating mechanisms; andthe anvil or former 4, which also by its engagement with the lipperforms the function of a gage to determine the position of the insolein the machine, may be, and preferably are, substantially the same asthe corresponding parts in the Letters Patent to John B. Hadawayhereinafter referred to, to which patent reference may be had for adetailed description thereof.

Referring now to the novel fabric trimming mechanism forming theparticular subject matter of the present invention, in the illustratedembodiment of the invention the knife operating mechanism of theHadathat is, the machine is provided with a horizontal rotary knifeshaft 5 suitably journaled in the carriage Gand driven by the engagementof a lug 7 on the rear end of theshaft, in a slot 8 formed in a drum 9carried b, a stud shaft 10 mounted to rotate in a bearing on a standard11 supported on the main frame, and driven by a belt-pulley 12. Thecarriage 6, with its adjustments, is the same in construction as thecorresponding part in the Hadaway patent except that the arm 13 is notprovided with a spring, a spring being unnecessary in the presentconstruction, and the stop screw s14 engaging the arm 13 are used foradifferent purpose than heretofore, as will be hereinafter explained.

At the forward end of the shaft 5 there is mounted a disk knife 15.Ahorizontally arranged plate 16 is secured by set screws to insole S andthe reinforcingplate 16 is the under side of the forward bearing for theshaft 5 and projects forwardly to a position below the knife. During theoperation of the machine the forwardend of the plate 16 enters betweenthe feather of the shown in Fig. 2, and its end portion cooperates withthe knife to secure a clean severance of the fabric and also holds thefabric in a position which enables a severance without danger of theknife cutting into the feather. To this end a spring 17 Y coiledaboutthe shaft 15 bearing at its forward end against the frame 6 and atits rear end against a collar 18 fast in the shaft, being similar to thecorresponding spring in the Letters Patent to John B. Hadawayhereinbefore referred to, operates to draw the knife toward the rear andhold its cutting edge yieldingly against the end of the plate.

Preferably, although not necessarily, the provided at its acting endwith a'transverse slot 19 in which the knife may rotate. The plate 16 isadjustably mounted in the frame 6 to permit the proper setting upadjustment between it and the knife to be made.

The mode of operation of the machine to attain the object of theinvention will be apparent to those skilled in the art. An initialadjustment of the screws 14:, for the size or style of sole beingoperated on, places the knife the proper distance from the operative endof the anvil or former 4 so as to effect a line of. severance spacedfrom the edge of the insole. The width of the feather in welt insolesvaries, the widest portionbeing at the shank and it is at the shank onlywhere a trimming of the fabric within the edge of the insole is mostessential. It will,therefore, be apparent that the present method oftrimming from the lip or rib of the insole as a gage, will prevent thefabric from being entirely removed from the feather along its narrowerportions while yet producing a severance inside the edge at the shank,as

shown at the left of the insole S in Fig. 9.. Having set the knife toits desired position the reinforcing operation is proceeded with in theusual way. The various forming tools, as in the machine of the Hadawaypatent, apply the fabric which is simultaneously trimmed by the knife.As is customary in machines of this type the upper surface of the plate16 will be oiled to prevent the sticky fabric from adhering thereto asthe insole is fed through the machine.

The present invention provides a simple and effective mode of gainingthe desired object by means readily applicable to the pres} entcommercial machine for forming a bead or crimp in the reinforcing fabricand securing it in place, in the process of making what is known as theGem insole.
